SPEED-REGULATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 433,529, dated August 5, 1890.

Application filed September 5, 1889. Serial No. 323,098. (No model.)

To all whom it may concern.-

Be it known that I, MADISON MAGINN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in a Speed and PowerRegulating and Governing Device, to operate in conjunction with a water-p0wer-developing device, for which I have made a separate application, Serial No. 296,777, filed JanuarylS, 1889. This governing device is a part of said water-powerdeveloping device and original invention as r set forth in my application as above referred to; and I do declare the following, when taken in connection with the drawings and the letters of reference marked thereon, to be a full, clear, and exact description of my device, and of which the following is a specification.

My invention relates to improvements in a device for regulating and governing the power and speed of a water-power-developing device in which a hydraulic or other suitable cylinder is arranged to operate a traveling frame or carriage, with a water motor or Wheel fixed thereon, same as represented in my application Serial No. 296,777, whereby the said water wheel or motor is regulated in depth of contact with the falling water and the speed and power of said wheel or motor are regulated and governed by this governing device; and the objects of my invention are, first, to provide ways and means whereby a hydraulic cylinder and piston operating and controlling the power and speed of a water wheel or motor can be controlled and governed and the speed regulated either automatically or at the will of the operator; second, to provide ways and means whereby the piston of a cylinder operated by pressure and operating or controlling the power and speed of a water wheel or motor in contact with and being driven by the weight and current of a body of falling water can be operated, controlled, and governed automatically or at the will of the operator; third, to provide ways and means whereby the piston of a hydraulic cylinder operated by pressure may be automatically governed or regulated, or governed .and regulated at the will of the operator. I

attain these objects by the mechanism illustrated in the drawings, in which- Figure 1 is a side elevation of a hydraulic out the several views.

The cylinder D, as here shown, represents the cylinder of a v. ater-power-developing device, detached for the purpose of clearly illustrating my regulating and governing device. Attached to the cylinder D is the governor J, of well-known construction, connected to and operating the valve K, controlling the inlet of the supply-pipe.

K is the supply-pipe receiving its supply from a steam force-pump located at any convenientdistance and direction from the device. (Not here shown.) Said supply-pipe, having its connection to the valve K at K passes through the open slot in plug N and is conveyed into the cylinder D through the pipes D K being'the exhaust-pipe, leads the supply out and away from the cylinder D after it has entered the same. This regulatingvalve K is constructed upon the principle of a six-way cock or rotary valve, M being the barrel with the different openings and pipeconnections upon its sides at D D, K and K &c., as shown The plug N of the valve K, being a single piece and moving assuch, is so constructed and arranged that the different openings, as D K D inlet-slots of the plug N, will, when placed in the barrel M, cover but one of the openings D of the barrel and retain a direct and open communication with the other openings D and K of the barrel M at one and the same time. A like arrangement with the same construction is employed in the slots or openings D K D of the exhaust portion of the plug N; but a difference of location in the plug becomes necessary, this difference being shown in dotted lines in Fig. 4: and open lines in Fig. 5. The necessity of this arrangement of openings in the plug is apparent from the fact that when the pressure is admitted to the rear of the cylinder and. forces the. piston-rod outward the exhaustslot D in plug N of the valve K must be open to permit the escape of the exhaust at K The action of the valve is the same in its reversing-movement, D being the supply-pipe feeding the cylinder D and located in a parallel line along the cylinder, and D the exhaust-pipe located close by and in a like mannertoD. 'Ihereforewhent-hesupplyinD islet in at one end of the cylinder D the exhaust D must be open, at the opposite end of thecylinder, and vice versa for the opposite movement of the piston. This is accomplished by the ar-. rangement of the slots in the plug N and the openings inthe barrel M of thevalve K, as

shown in elevationand details, Figs. 3, 4, and 5. Projecting through. theend of the valvescasing M, at N is the stemiofthezplug. .N.- Upon this stem, at N, is placed .anoperating-lever N which' can'eitherbe operated by hand or. automatically by the governor J. v For oper ating thevalve by the governora connection is made to the operating-lever J 4 of. the gov:

ernor by. the rod N one endof which is connectedto oneof two arms fixed at rightangles' upon a pivoted rocking sleeve Nt. Said arms have an alternating movement given by the governor J through its connection .toa rocking. sleeveoperating upon a stud pre-v pared for this purpose.

*valve K, as will be further explained. in the description of the governor. I have shown.

here connected to the valve. and cylinder of my devicetheordinarygovernor, consisting of twoheavy balls suspended by links from a spindle,and caused to revolve, either by belt or shaft connection, with the shaft of the motor. In thedrawing, the governor is driven by belt-connectionto the pulley J bevelgeared tothegovernor. When at rest, the balls hang close to the spindle, butwhen in motion the balls rise by centrifugal force, When the motor is running at .its established speed, the linksassume a position nearly at forty-five degrees with the spindle. If the speed falls, the balls fall, and actingon the leverJ (shown. in side view) open the valve One of these alternating arms is connected ,to the operating. lever N of thev valve K, as shown in Figs, iVhen the governor transmits ,its'.

K, controllingthepassageway to the cylinder D.- .If the speed rises, the balls'rise and close the valve or act directly upon its equivalent, thusoperating the valve K automatically. The lever J 4 may be connected direct to the valve K by placinghthe valve K in a sleeve with the stationaryarms fixed at right angles upon the same.

I am aware that .prior to my invention govton .and lift valves are operatedby. a stroke movement and operating. in conjunction with. elevator-hoists, &c. .To-this methodI donot lay any claims.
